中文摘要:
      随着数字信息技术的快速发展,数字图像信息被广泛用于通信和信息的表示,但该类信息也常常会受到非法的篡改,因此如何保证数字图像的版权不被破坏是数字信息领域一直面临的问题。数字水印作为一种版权保护技术,能在一定程度上解决图像的版权纠纷问题,对数字图像技术的研究具有重要的意义。本文对近些年来国内外学者在该研究领域取得的成果进行了系统总结,首先给出了图像水印的基本模型、基本特性以及衡量指标;接着,分析了现有的数字图像水印算法特点,并进行分类,介绍了水印技术在其他领域的应用;然后,针对水印算法的抵抗行为,总结了现有水印算法能有效抵抗的鲁棒性攻击;最后,根据现有水印技术的优势和不足,提出未来的发展趋势和下一步研究的方向。
英文摘要:
      With the rapid development of digital information technology, digital image information is widely used in communication and information representation, but such information is often subject to illegal tampering.Therefore, how to ensure that the copyright of digital images isn’t destroyed is a problem that has been faced in the field of digital information.As a copyright protection technology, digital watermark can solve the problem of copyright disputes of images to a certain extent. For this reason, the research on digital image technology is of great significance. This paper systematically summarizes the achievements made by scholars at home and abroad in this research field in recent years. First, the basic model, basic characteristics and measurement indicators of image watermarking are given. Then, the characteristics of existing image watermarking algorithms are analyzed. This paper classifies and introduces the application of watermarking technology in other fields. Next, based on the resistance behavior of watermarking algorithms, it summarizes the robust attacks that can be effectively resisted by existing watermarking algorithms. Finally, according to the advantages and disadvantages of existing watermarking techniques, future development trends and the direction that can be studied next are proposed.
